How can I design an 13.56 rfid antenna with cst

Hi all
I'm beginner in CST (in fact very beginner!, we bought its cd two days ago)
My project is design and implement an antenna for work in 13.56 MHz frequency.
I see name of CST on many article on the web and I have very low knowledge about CST and its facilities about designing rfid antenna. Can anyone help me about features and facilities of CST that useful for designing antenna? Or any document help me about CST introduction? Hope to answer please.
Best Regards
SNI

Its seems that really no one work on rfid in this forum or maybe don't like to share our knowledge.
In any cases, thank you for regarding.

For lowfrequency you need first a loop antenna calculator.

I think kindly you don't understand me.
I speak about RFID technology Antenna Design not anything ever
However, thank you so much for your reply
With regards
